JOHN W. WHITCHER, OF CBOSTON,MASSAGHUSETTS.

BELT-CLAMP.

.a-citizen of the United States, residing at;

Boston, in the=county of Suffolk and State;

of Massachusetts, have invented certain new; and useful Improvements in Belt-Glamps,f

of which the following is a specification.

This invention relates to belt clamps. The object of-the inventionis to improvefi generally the construction of belt clamps so;

that the clamps may easily be applied to; belts to tighten the same and so that the: clamps may be easily and quickly removed; from the belts without'detaching the nuts from the various bolts andscrew-rods, and; withoutthe necessity of employingithe services of moretthan one-man in the application of the clamps or the removal thereof? from the belt. g With the above and other objects in View? the present invention consists in the combi-f nation and arrangement of parts hereinaf-i ter more fully described, illustrated in the accompanying drawings and particularly pointed out in the appended claims, it being;

understood that changesmay be made in the form, proport1on,s1ze and minor detalls without departing from the spirit or sacri- ,ficmg any of the advantages of the invention. p v

In the drawings :Figure 1 is a top plani view illustrating the application of my in-; vention. Fig. 1 is a detail plan .view of a portion of theclampshown in Fig. 1. Fig

2 is a side view of one of theclamps with the belt removed therefrom. Fig. 3 is a side view of one of the clamps partly in. section illustrating the position of the? clamping members in dotted lines when it is; desired to apply the clamp tothe belt or tof remove it therefrom; "Fig. 4 is aview of al modified form of clamp partly in side view: andpartly in section. 1 I

Referring now more'particularly to the accompanying drawings the reference character 1 indicates a belt whose ends are con-: nected together by lacing orotherwise as indicated at 2, the belt being held between clamps A and B, each clamp A and B, as shown in Figs. 1 to 3, inclusive, being the same in construction, thereby necessitating Specification of Letters Patent.

The

characters

3 and 4 indicate upper and lower clamping members, respectively, each having its inner face notched to 'provlde end slots a and b for a purpose presently the

clamping members

3 and 4.

The character 5, indicates a pin passed transversely through one end i of, the lower clamping member land throughthe slot 0 and on which'pin 5 the eye-bolt 6 is secured explainedthese slots (1. and Z2 being arranged horizontally. with referencejto the clamp, I the slot a .intersecting a vertical slot, 0 formed by bifurcating oneend of each of,

and whereby the eye-boltmay be swung into and out ofrthe vertical slot 0, there being a'nu-t and

washer

7 and 8, respectively, secured on the outer end of the eve-bolt 6 for the purposeof holding the ey'e bolt in such posltion. with reference to the clamping members 3and t as to provide for an efiicient clamping :ofthe belt .1 between the clampingmembersq r Secured to the under face of the lower clamping'member & is a metallic or other plate .9 provided with a rectangular opening adapted toaline with the openings 10 :and 11 of theclamping

members

3 and 4 and through which openings" is passed the bolt 12 whose shank adjacent its head 13 is squared as indicated at 14 to fit in the square opening of the plate 9 to prevent turning of the-bolt 12, there being a nut and washer 15 and l6, respectively, secured to the bolt 12 to insure clamping ofthis particular end of the clamp on the belt.

Secured to the outer sidefaces'of the clamping members 3Ian d 1 at each end thereof-is a plate 17 provided with'ja lug 18, there thus being apair of plates 17 carried by each clamping member and 'it will be seen that the lugs 18 of opposing plates of cooperating clamping members are ar-,

ranged preferably in alinement for the pur pose of preventing turning of thenuts 19 carriedby the

screw rods

20 and 21 which latter are fitted in the aforesaid horizontal slots a and I), respectively. Thescrewi'ods 20 and 21 are preferably made in 'one'piece, provided with right and left screw-threads and nuts upon opposite ends and an enlarged portion (Z, intermediate the ends to provide means to turn said rods. It is obvious that each of said rods might be made in two parts with their threaded ends connected witha turn-buckle in the center in the usual manner, if so desired. By virtue of the nuts 19 at the ends of these

screw rods

20 and 21 engaging the lugs 18 of the plates 17 the nuts cannot turn and therefore it is unnecessary to have two ,men ma nipulate the clamp when tightening the belt, that is, one man for operating the screwrods by the enlarged portion d and another man or men to prevent turning of the nuts 19.

When it is desired to remove the clamps from the belt it is simply necessary to slightly slacken the nut 7 on the bolt 6, when the clamps will loosen on the-belt and the screw-

rods

20 and 21 are thereby freed from any strain and may be readily removed intact. It is .thenonly necessary to a little farther unscrew the nut 7 on the bolt 6 when the latter may be thrown out to the dotted line position indicated in Fig. 3 and the upper clamp 3 elevated as shown in dotted lines in Fig. 3 when the clamp may be moved laterally away from the belt, thereby obviating the necessity of com pletely swinging the clamping member 3 around from over the clampingmember 4: on the bolt 12. It will be seen that the openings 10 and 11 of the clamping mem-- here are elongated with their greater diameters extending longitudinally of the clamping members, said elongated openings having their greater diameters increasing in length throughout the thickness of the clamping members. This is done to give the bolt 12 considerable play to allow the two parts of the clamp to be openedas indicated in dotted lines in Fig. 3 so as to readily apply the clamp to the belt or permit removal of the clamp from the belt, the clamping members 3 and 1, in other words, having not only movement away from each other at one end but also, by virtue of the elongated openings 10 and 11, having slight longitudinal movement upon each other so as to insure ready application of the belt by the clamping members or removal of the clamping members from the belt.

In Fig. a there is shown a little different type of clamping member wherein the clamping members 3' and 4: are each notched at each end to provide the horizontal slots a and Z) corresponding'to the slots a and 7) of the preferred form of the invention. The clamping members 3' and 4c are also provided with openings 10 and 11, respectively. The openings 10 and 11 are elongated similar to the openings 10 and 11 of Figs. 1, 2 and 3, but the opening 11 has its smallest diameter equal to the largest diameter of the opening 10 so that when the clamping members 3 and 1 are superimposed the openings 10 and 11 aline so that an opening is formed which increases in size from the top of member 3 down through the bottom of member 1, as clearly shown in Fig. 4. Through the openings 11 of the lower clamping member 1" is passed a pin 5 on which the hook bolts 22 are secured, there being nuts 23 and washers 24 disposed on the hook bolts 22 to insure a binding engagement of the clamping members 3 and 1- on the belt.

While the last form described is not the preferred one, it is one that is very convenient and easily operated.

hat is claimed is 1. A belt clamp comprising clamping members each provided with vertical openings, said openings being elongated with their greater diameters extending longitudinally of the clamping members and said openings having their greater diameters increasing in length throughout the thickness of the clamping members, said openings having one end of each in mutual alinement.

2. A belt clamp comprising clamping members each providedwith vertical openings, extending through the clamping members, said openings being elongated and increasing in size from one surface of the clamping member toward the opposite surface, with the greater diameters disposed longitudinally of the clamping members, said openings having one end of each in mutual alinement.

3. A belt clamp comprising two superimposed clamping members provided with vertical openings disposed near one end of each member but spaced therefrom, said openings being elongated and increasing in size from one surface of the clamping members toward the opposite surface with the greater diameters disposed longitudinally of the clamping members, bolts slidably mounted within the openings of the clamping members, the inner wall of each of said openings being straight and substantially perpendicular to the body of the clamping members with the opposite wall inclining downwardly and outwardly to permit movement of the free end of the clamping mem bers relative to the other when the bolts are loosened.

1. A belt clamp comprising two superimposed clamping members detachably secured together at one end each having a vertical opening at its other end, a bolt passing through the openings in the clamping members, and means to secure the bolt insaid openings, said openings being spaced from the ends of the clamping members and having their inner walls straight and in vertical alinelnent with each other, with rated without withdrawing the bolt at its their outer walls inclining downwardly and other; end. 10
